  The plate portion guide body 46 guides the lower end portion of the plate portion 43 of the operation body 45 in the horizontal direction. For example, the plate portion guide body 46 is horizontally disposed on both the left and right sides in the storage tank 3 and is disposed in parallel with each other in the longitudinal direction. A plurality of, for example, two guide members 47 are used. The front end portion of the guide member 47 is fixed to the lower end portion of the oil / water separation plate 31 and is fixed to the lower end portion of the partition plate 11 of the guide member 47.

  Next, the operation and the like of the oil recovery device 1 will be described.

  As shown in FIG. 2 and the like, the waste water discharged from the sink tank portion of the business sink flows through the connection pipe 2 and flows into the storage tank 3.

  The drained wastewater is temporarily stored in the storage tank 3, and the oil in the drainage is removed by floating separation due to the difference in specific gravity with water, and the floating and separated oil becomes floating oil a.

  At this time, the operating body 45 is placed in the standby position with the handle portion 42 placed on the central portion in the left-right direction of the upper end portion of the front plate 7 and the plate portion 43 placed on the guide member 47 of the plate portion guide body 46. The substantially lower half of the plate portion 43 is positioned below the surface of the drainage.

  For example, when the floating oil a in the storage tank 3 reaches a predetermined amount or more, the operator moves the floating oil a in the storage tank 3 into the oil recovery body 4 using the operation body 45.

  That is, as shown in FIG. 5, the operator first holds the handle portion 42 of the operation body 45 and pulls the entire operation body 45 toward the front so that the vertical plate portion 43 faces the oil / water separation plate 31. It slides forward while being in contact with the guide member 47 along the guide member 47 of the plate portion guide body 46 until it comes into contact with the oil / water separation plate 31.

  At this time, the floating oil a is pushed up along the flat plate portion 35 of the oil / water separation plate 31, gets over the oil / water separation plate 31, is guided by the oil guide plate 41, and falls by its own weight into the oil recovery body 4. Collected. A part of the drainage flows through the drainage recess 33 of the concavo-convex plate portion 36 of the oil / water separator plate 31 and escapes downward as indicated by the arrows in the figure.

  Subsequently, as shown in FIG. 6, the operator holds the handle portion 42 of the operating body 45 and pulls it while lifting the entire operating body 45 toward the front, so that the plate portion 43 having the forward and downward inclined shape is placed in the oil water. The oil-water separator plate 31 is slid upward along the separator plate 31 while being in contact with the oil-water separator plate 31.

  At this time, the floating oil a is pushed up along the connecting plate portion 34 and the flat plate portion 35 of the concavo-convex plate portion 36 of the oil / water separator plate 31 while being supported from below by the plate portion 43 of the operating body 45. After overcoming the separation plate 31, the oil is guided by the oil guide plate 41 and dropped into the oil recovery body 4 and recovered. Since a part of the drainage is heavier than the floating oil a, it flows through the drainage recess 33 of the uneven plate portion 36 of the oil / water separator plate 31 and escapes downward as indicated by the arrow in the figure.

  Then, as shown in FIG. 7, the operator stops the operating body 45 when the lower end portion of the plate portion 43 of the operating body 45 reaches the upper end portion of the oil / water separation plate 31. Then, the floating oil a on the plate portion 43 of the operating body 45 is transferred onto the oil guide plate 41 and dropped by its own weight into the oil recovery body 4 and recovered.

  When the recovery operation of the floating oil a in the storage tank 3 into the oil recovery body 4 is thus completed, the operator returns the operation body 45 to the original standby state. For example, the worker periodically performs the above-described recovery operation of the floating oil a.

  According to such an oil recovery apparatus 1, after the operator moves the plate portion 43 toward the uneven oil / water separation plate 31 by manually operating the operating body 45 while holding the handle portion 42. When the oil water separation plate 31 is moved up in contact with the oil water separation plate 31, only the floating oil a in the storage tank 3 is pushed up along the oil water separation plate 31 while letting the waste water escape into the storage tank 3. 41. Since the structure is such that the oil is recovered by being dropped onto the oil recovery body 4 through 41, the floating oil a is appropriately and efficiently recovered by the oil recovery body 4 despite the simple structure and low manufacturing cost. be able to.

  In addition, since the plate portion guide body 46 that is disposed in the storage tank 3 and guides the plate portion 43 of the operation body 45 is provided, the plate portion 43 of the operation body 45 is directed toward the oil / water separation plate 31 to the plate portion guide body 46. It can be slid along properly and smoothly.

  Furthermore, since the oil / water separation plate 31 has a plurality of drainage escape recesses 33 arranged in the horizontal direction only at the lower portion, it is possible to appropriately suppress the wastewater from being collected in the oil recovery body 4 together with the floating oil a.

  Further, since the oil / water separation plate 31 is disposed in the storage tank 3 in a steeply upwardly inclined manner with respect to the horizontal direction, only the floating oil a in the storage tank 3 can be recovered more appropriately. .

  Note that the plate portion 43 of the operation body 45 is not limited to a substantially rectangular plate shape, and may be a substantially L shape in a side view as shown in FIG. 8, for example. The substantially L-shaped plate portion 43 shown in FIG. 8 includes a vertical first plate portion 43a and a horizontal second plate portion 43b protruding forward from the lower end portion of the first plate portion 43a. The second plate portion 43b includes a protrusion 43c that protrudes obliquely upward from the front end portion.

  Further, the operating body 45 is not limited to the one in which the handle portion 42 is attached to the plate portion 43 via the connecting arm portion 44.

It may be directly attached to the central portion in the left-right direction of the upper end portion of the first plate portion 43a.

  The operation body 45 shown in FIG. 9 and FIG. 10 is provided outside the storage tank 3 with the upper ends attached to the left and right ends of the upper end of the first plate part 43a of the plate part 43, and the side plate of the storage tank 3 9 and 10 has a regulating portion 51 for preventing the displacement of the left and right position in the longitudinal direction that regulates the movement of the operating body 45 in the left-right direction by contact with the outer surface.

  Each restricting portion 51 is bent at a substantially right angle to form a bent portion 52, and this bent portion 52 is fixed to the left and right end portions of the upper end portion of the first plate portion 43 a of the plate portion 43. ing. The bent portion 52 of the restricting portion 51 is placed on the upper end portions of the side plates 9 and 10 of the storage tank 3 and slides along the upper end portion. That is, when the operator manually operates the operating body 45 to horizontally move the plate portion 43 toward the oil / water separation plate 31, the bent portion 52 of the restricting portion 51 is formed on the side plates 9 and 10 of the storage tank 3. It slides along the upper end on the upper end. At this time, the operation body 45 is not displaced in the left-right direction due to the contact between the restricting portion 51 and the side plates 9 and 10.

  Note that the oil recovery apparatus 1 shown in FIGS. 9 and 10 is configured not to include the plate portion guide body 46 because the upper end portions of the side plates 9 and 10 serve as guide portions for guiding the operating body 45. ing.

  Further, for example, the handle portion 42 is directly attached to the central portion of the upper end portion of the substantially rectangular plate-shaped plate portion 43 shown in FIG. 2, and the restricting portions 51 are attached to both end portions of the upper end portion of the plate portion 43 in the left-right direction. The structure etc. may be sufficient.

  Furthermore, the oil / water separation plate 31 is not limited to the one in which only the lower part is formed in an uneven shape, and may be one in which the whole is formed in an uneven shape. That is, for example, having a plurality of longitudinal drainage recesses located from the upper end to the lower end of the oil / water separator plate 31, or a substantially hemispherical protrusion located in a distributed manner only on the entire or lower part of the oil / water separator plate 31. You may have more than one.
